JERSEY, A CORPORATION OF NEW J 1 rEN- Application filed December 23, 1326. Serial No. 156,566.

Our invention relates to that type of writing pens particularly adapted for the production. of relatively broad lines ofuniform,

width; such pens being employed by sign writers, engrossers, and the like, andthe principal object of our invention is toproa at will in order to insure proper feed of inks,

of various consistencies.

.A further object of our invention is to provide the reservoir forming. element with a rounded tip at the extremity of the same from which the ink normally sustained or retained by said element with respect to the pen may flow to the nibs ofthe' latter as said nibs are flexed or spread during use.

A'further object of our invention is to provide the reservoir forming element with a rounded tip at the extremity of the same with an upturned rim or lip; such rounded end presenting 'a substantially cup-shaped contour or form.

And a still further object of our invention is to provide such reservoir forming element with an elongated opening extending substantially to such rounded tip. d I

These and other features of our invention are more fully described hereinafter; referencebeing had to the accompanying drawings, in which: 7 V o v Figure 1 is a front elevation of a pen equipped with the reservoir-forming attachment constituting our invention.

;Fig. 4 is an enlarged sectional view of the pen and its reservoirattachmentin position of use; illustrating also the'body of ink held by capillary attraction between suchrese'rvoir attachment and the pen. g 1

.Figs. 5 and 6 are cross sectional views on.

the lines VV and VIIVI, Fig. 4?, respectively. I ,Fig. 7 is a front elevation of a portion of a pen and the reservoir forming element show mg a modification ofthe rounded tip particularly applicable to pensin which the writing end or spoon is split intomore'than two points orlnibse v 3 Fig. -8 is a sectional view on the line VIIIVIII, Fig. 7, and

Fig. 9 is "a view similar to Fig.7, showing the application of a] reservoir f orming ele-' ment having a cup-shaped tip to a pen having a writing spoon ofa dilferent shape.

. The pen proper may be of the type illus trated in the prior patent of Edward S. Wood, No. 1,305,046, dated May 27, 1919; comprising a. substantially semi-cylindrical body 1, with the usual shank 2, for engagement with any suitable form of holder, and having'the usual eye 3, forming the upper termination of a slit 4;, which bifurcates the point to form the separate nibs 5 and 6, which are extended obliquely outward and are complementary to form the ink dispensing spoon consisting of the upturned ends 5 and 6 of such dimensions as may bedesired.

:It is desirable in the use of'pens of this character thata reservoirdevice be employed therewith, in order that a steadyand constant flow or supply of ink for considerable shown in Fig.1, of the drawings.

When employed with pens having more than one slit; thereby providing more than one nib, it is desirable'to insure that the flexof the pen. It hasbeen found, however, that In ,the pen illustrated in the accompanying drawings, the up-turned end portions are sub-.

stantially semicircular in contour, capable of producing a line having circular terminals,

althoughit will be understood that such end portions may be of different shape. without departing from our invention. As in the patent referred to, the so-called spoon formed by the upturned nib ends 5 and 6 is disposed in oblique relation to the axis of the body of the pensoas to be parallel to and in flat engagement with the surface tov be scribed when said axis isdisposed at an angle approximately to the plane of such sur face. i

Carried by the pen is a flatfinger 10, overlying the same in the position clearly illustrated in the drawings, and this finger may be provided with springclips or wings 11, adapted to embrace the pen body adjacent to the shank 2, whereby said finger may be held in inclined relation to the outer-surface of the pen body and across the eye 3 of the same. This finger is provided with an elongated aperture 12, somewhat wider at the rear portion than at the forward portion, which aperture extends into and relatively close to the graduallytapered' part 10 of said finger 10; said tapered part being disposed within the sidemargins of the pen so as to be out of the way when the pen is used for ruling purposes "by contact with a straight-edge, and this narrowed portion ofthe finger terminates in.

a substantially circular end 13, overlying the nibs 5 and 6, just short of the upturnedends 5 and 6 of the same The common practice heretofore in'the use of reservoir-forming elements of this type, and as indicated 'inthe prior patent before referred to, is to have the narrow terminal of-the finger in actual contact with the nibs V inksvary greatly in consistency and fluidity,

and it is frequently objectionable to have this contact sincein the thicker inks it tendsto,

slow up the flow and in some instances, out it off entirely when the engaging portions 5 and 6 of the nibs are in actual contact with p the card, paper or'other object upon which the line is scribed. An important object. of

our invention, therefore, is to provide this TBSQIVOIIFfOIn'llIlg finger in spaced relation with respect to the pen so as to prevent this slowingupor cutting: off of the flow.

Additionally, thefingeris preferably made of :nonferrous metal'that may be more or less readily flexed; German silver being preferred, and the user is able to increase or decrease the amount of separation between said finger and the nibsof the'p'en and insure ready flow to the spoon constituted by the upturned portion of the nibs 5 and 6 The flow of ink from the reservoir is also. faciIitatedf-bythe presence of the extended aperture or slot 12 in said finger, and by the narrowing' of' such finger and its termination inthe rounded end 13;

WVhile we have described and shown a pen having a rounded writing spoon or table formed, by the. up turned ends 5 and 6 of the nibs 5 and. 6, it will be understood that such table or spoon may be square, rectangular or other shape suitable for the purposedescribed, and in someinstancesmay beom-i-ttedaltogether.

In Figs. 7, 8 and 9, we have shown a reservoir forming element particularly applicable-to pens having more than one slit;

Fig. 9, showing also a pen having a rectangu-- lar writingend. To avoid danger-of the side-nibs catching on therounded end-of the reservoir forming element, the edge or rim of the-latter may be turned up slightly to cup-shape, as indicated at 13 these views-be ing enlarged to show clearly this feature of our invention. In somev instances, only the sides of the rounded ends may be turned up- WVe' claim-z a 1. The combination with a pen having, the free. endsof its nibs extend-ed at angle to the axis of the body to form a writing table, of a fiat reservoir-forming finger made of freely flexible non-ferrous. metal permanen-tly securedto the upper: side of the pen body and spaced therefrom; the distance between the pen body a-nd said reservoir-forming finger being greatest. at a. point remote from said writing table. and gradually approaching, the latter andsaid'finger being ta-Z pered in substantial conformity with and overlying;-the nibs of the pen and laterally spaced. from the marginal edgesof'ithe same b and forming anarrow neck, with acircular end joined to said neck. and disposed adjacent to the angularly disposed nib extensions forming the writing table and out. of contact with said pen. f v

2. The combination with a'pen slitted' to form a plurality of tapering nibs terminating in end portions extended at an angle to the axis of the hodyito form a writing table of greater width than said nibs, of a flat reservoir-f'orming finger made of non-ferrous" flexible metal permanently secured to: said pen. and free for adjustment from auditoward the nibs of the same;- said finger'having a taperingneek .portionlaterally-spaced from themarginal-ed'ges of the pen nibs-with an elongated tapering aperture overlying;

the slit between the nibstand. extending close to its end which terminates in a eircularpor tion oined to said tapering neck; the opposite sides of said circular portionexten'ding to the marginal edges of the pen nibs just short of the angular extensions thereof.

In Witness whereof We have signed this specification.
